ABSTRACT:
A rack and pinion steering gear assembly 10 includes a rack 14 which is movable relative to a housing 12 to turn steerable vehicle wheels. The rack 14 extends through a bellows 34 which is connected with an end portion of the rack 14 and an end portion of a housing 12. A deformable and compressible body 40 of foam material is located in the bellows 34. The deformable and compressible body 40 of foam material includes a body 70 of closed-cell foam 10 material and/or a body 66 of open-cell foam material. The body 70 of closed-cell foam material retards conduction to the rack 14 of any water which may leak through the bellows 34. The body 66 of open-cell foam material contains lubricating liquid which is applied to the rack 14. If desired, the bellows 34 and deformable and compressible body 40 of foam material may be used in an apparatus other than a rack and pinion steering gear assembly.
